Cell phones are now powerful enough to support and visualize maps, image and other complex information however screen is still small to support its portability. Exploring geographical information on small s screen is still a big challenge and one can’t conceptualize and get all information at once on small screen.Overview + detail technique is common and widely used to explore large information however there are problems associated with it that is overview window hide some information from detail window and movement between two windows is not seamless. To handle these problems modified split screen technique is presented in this paper that has large overview window and provides detail window on toggle mode to provide unobtrusive behaviour and continuity while exploring the information contents on mobile screen. Experiment is conducted to compare both techniques: overview +detail and split screens. Results shows that with simple spatial tasks no differences surfaced for two technique...

Since the 1990's, Business Intelligence (BI) which is the activity of intelligently gathering, integrating, storing, processing and analyzing business data in order to find out pertinent and meaningful information to improve business decision making, has been massively adopted by decision makers. Meanwhile, Geospatial BI (GeoBI) systems, by providing spatio-temporal data support, cartographic visualization and spatial analysis capabilities, has specifically improved the capacity to analyze the state of business on the field and make well informed decisions ([1]). However, as BI and GeoBI systems rely on fix, cumbersome and client/server technologies, they are not suitable for mobile workers whose number is increasingly growing. To give an improved support to these mobile workers, it is necessary to go further than just allowing a simple remote access to a business intelligence platform (as do most of the present commercial solutions). An actual context-aware and location based mobile GeoBI system that fully takes into account the specificities of mobility (opened and dynamic workspace, working while moving, mobile technologies are specific, etc.) is required. In this prospect, understanding and handling the contextual information in the scope of mobile business intelligence is important given that context-awareness relies on it. The proposed paper deals with mobility and mobile context in the scope of decision making. First, mobility is scrutinized through two points of view which pertain to the decision making domain, namely: the information technology side (mobility as remoteness) and the user experience side (mobility as dynamic change of context). Then, key elements that could structure a mobile business context (such as personal context, social, spatial, temporal, business and technological contexts) will be explored and several models will be proposed in order to improve context and situation awareness in decision making. 2.UNDERSTANDING MOBILITY Depending on the thematic, the concept of mobility has been described or understood differently by various authors. Among the various acceptations of this concept, the following have been proposed: >> Mobility according to the activity Authors distinguished professional mobility ([2,3])-mobility of workers-, from social mobility-daily mobility of people-([4,5]). According to [6a], professional mobility can be partly explained (i) by the emergence of service-based jobs in a post-industrial society, (ii) by the strengthening of intra and interorganizational cooperation, and (iii) by the popularization of mobile devices. >> Mobility according to the distance Depending on the perimeter, [3] distinguished micro, local and remote mobility. Relying on this work, [6] proposed a classification of mobility into three instances: (i) traveling, i.e. moving from one place (e.g. a city) to another one using transportation (car, train, plane, etc..); (ii) visiting, i.e. spending some time in a place before moving to another one, such as a mobile worker who spends a week working in a city, and (iii) wandering, a local mobility which consists of patrolling, touring or walking within a building or a small space. Considering the mobility as a travel, [5] has identified 4 classes of mobility: physical mobility of inanimate objects, imaginative mobility, virtual mobility in a digital world, and physical mobility of humans. >> Mobility as interactions Given that social relations and the need to physically interact with other persons are involved in the justification of mobility, mobility is not then only a geographical and temporal displacement, but also concerns how the person who moves interacts with his environment and other persons ([7]). In this context, [8] provided a classification of mobility into three dimensions: spatial mobility ("where?"), temporal mobility ("when?") and circumstantial mobility ("in which way?", "under what circumstances?", "in interaction with which actors?"). Alongside these various taxonomies, mobility has to be also scrutinized under two additional viewpoints which pertain in decision making domain, namely: the information technology (IT) side (mobility as remoteness) and the user experience side (mobility as dynamic change of context). These two perceptions of mobility are presented in the following sections.

This chapter focuses on the development of mobile applications in a research strategy that combines computer sciences and architecture and urbanism. The main goal of the research is to develop mobile applications that help specific target people in daily life situations and that clearly contribute for advances in the fields of computer sciences and social responses. The authors discuss a group of mobile apps that were developed for smartphones and tablets and that respond to the following broad goals: 1) mapping of the physical space in order to adapt it to respond better to the users' needs, 2) adaptation of the physical space to the users' needs, and finally, 3) give the users a better knowledge about the physical space they are in. For each app developed, the authors describe the research problem involved, the goals, the development process, and the developed solution as well as the tests conducted to measure their performance. Usability and satisfaction tests revealed that the developed apps have a good acceptance by the target users.

Nowadays it can be seen that the average length of holiday trips (in number of days) tends to decrease, so tourists have less time to spend and therefore they need to plan their holydays better. In order to do this, there are several software tools for the organization before the trip, and for scoring it at the end. However, there are very few software tools that help tourists during their stay. During the trip, tourists need to locate the places of interest for them, according to their preferences, and close to them in a quick and comfortable way, for example through the use of mobile devices for geolocation. It is also important that the proposed places and the way to show this information have been adapted for people with disabilities. The Laboratory of Information Technologies and Multimedia is developing the MediaTurDownloader project, an accessible application for geographic location via mobile phones that allows tourists to know at any moment the situation where they are and ...

Providing indoor navigation within ab uilding is usually associated with large investments in infrastructure. We present and evaluate an approach to provide indoor navigation with minimal infrastructure investments. In our approach people use amobile camera device likeamobile phone as amagic lens. When the device is sweeped overam ap of the building, the wayi sa ugmented on the camera image of the map. We showthat people using our system use more maps and makeless errors. The main advantage of our approach is that no tracking of the user is needed-t he navigation is solely based on the user'smobile phone and paper maps. 1I ntroduction Everyone can remember asituation when he entered an unfamiliar building looking for a certain person. Probably the room number is known, butthe unstandardized building plans are difficult to read. The signs pointing to certain departments are difficult to interpret, and manypeople fall back to social navigation and ask someone. But if the building is big, it is improbable that the person asked knows the way. In the scenario we propose the first action upon entering the building would be to takeone'smobile phoneand point it to the next building map. It would be possible to select the person one is looking for from alist or ap oster with the employees' photos. The wayt ot he selected person would then be displayed on the camera image of the buildings' map. If maps are provided at all decision points within the building, the correct wayw ould always be available. To evaluate our approach we implemented aprototype of the system on an OQO 1 and tested the prototype with users of different familarity levels with the building.
